SHUTTER-OPERATOR.

Specification of Letters Patent No. 27,458, dated March 13, 1860.

To all whom it may concern:

Be it known that I, EDWARD MATTooKs, of Lyndon, in the count-y ofCaledonia and State of Vermont, have invented a new and usefulImprovement in Operating TWindow Blinds, Shutters, &c.; and I do herebydeclare that the same is fully described and represented in thefollowing specification and the accompanying drawings, of which- Figurel, denotes a front elevation of a window frame having a blind appliedthereto and provided with my improvement. Fig. 2, is an inner sideelevation of the window fame showing the head of the guiding tube. Fig.3, is a side view of the guide tube to be hereinafter described.

The nature of my invention consists in applying to a window frame andblind, certain. devices (as hereinafter set forth) for controlling themovements of the said blind, whereby it may be unlatched, opened oiclosed, and relatched, without the necessity of raising' the sash of thewindow.

In the drawings above mentioned, A, represents a window frame (providedwith a sash) and having a blind, B, hinged or applied thereto in theordinary manner. From the lower side of the said blind, a spring catchbar, D, is attached, the same having a double catch, (o, a, constructedand disposed upon its outer end inthe usual way. Near the lower part ofthe window frame, A, and transversely thereof, a hole or passage, c, isformed, and within the same a cylindrical pipe is placed, and properlysecured.

Through this latter pipe, the longer arm, (Z, of a rectangular tube, C,is disposed, the same being of such size as to be capable of beingreadily revolved, as well as slid longitudinally therein. On the innerend of said longer arm, (Z, a button or milled head, e, is secured, thesame being for the purpose of actuating the said tube, C. The object ofthis peculiar formation and arrangement of the tube, C, is to obtain aready means whereby, by the use of a single tube and cord, the line oftraction may be varied so that the blind may be either drawn toward thewindow, or pulled backward therefrom,

as circumstances may require. Through the said tube a cord or rope, f,is carried and has one end attached at or near the outer part of thespring bar, D, or that which carries the double catch, the other end ofsuch cord projecting from the button or head, o, as seen in Fig. 2.

Having thus described the construction of my invent-ion, I will nowdescribe its operation.

If we suppose the blind to be closed, and we desire to open the same andfasten it back or to the side of the building, to which it maybeapplied, we iirst grasp the button, e, on the inside of the windowframe and push the tube outward; we next pull on the cord suiiicientlyto slightly depress the spring catch bar, D, or enough to throw thecatch out of engagement with its fastener; next we cause the tube tomake one half of a revolution, or move through an are of ninety degrees,the shorter arm of the tube sweeping downward in the movement; next,pull upon the cord to cause the blind to swing around or into a properposition for being locked or fastened; next draw in the tube and cord,and the operation is completed.

From the above it will be seen that the object aimed at, is accomplishedin a simple, easy, and edective manner, and that the mechanism employedis also very simple, and not liable to derangement.

Vhat I claim is- The combination of devices herein set forth, forcontrolling the movements of a window blind, whereby it may beunlatched, opened or closed, and relatched, (as circumstances mayrequire) such devices being the rectangular tube, C, the spring catchbar, D, and the cord, f, the same being arranged and made to operatetogether, substantially in manner as set forth.

In testimony whereof I have hereunto set my signature this 25 day ofJuly A. D. 1859.

EDWARD MATTOCKS.
